People who take Januvia, Byetta (BY’-yet-uh) or certain other widely prescribed medicines for diabetes can breathe a little easier. U.S. and European regulators say they have found no compelling evidence of a link between these drugs and pancreas problems.

The federal Food and Drug Administration and its European counterpart started reviews last year of these medicines after a study suggested a safety concern. They include Janumet, Victoza, Bydureon and other brands. The drugs help spur insulin production after meals, to help people with Type 2 diabetes break down carbohydrates in food.

In an article in Wednesday’s New England Journal of Medicine, FDA and European scientists say their review provides reassurance but that a final conclusion has not been reached and they will continue to investigate concerns.
